Why AAON (AAON) Shares Are Plunging Today

What Happened?

Shares of heating and cooling solutions company AAON (NASDAQ:AAON) fell 15.3% in the morning session after the company reported disappointing second-quarter 2025 results that missed analyst expectations for revenue and profit, and provided a weak outlook for the upcoming quarter. The heating and cooling solutions company reported revenue of $311.6 million and adjusted earnings of $0.22 per share, falling short of Wall Street's estimates of $325 million and $0.33 per share, respectively. Furthermore, its revenue guidance for the third quarter came in 14.3% below analyst expectations, signaling continued headwinds. Profitability was a major concern, as the company’s operating margin collapsed to 7.6% from 21.7% in the same quarter last year. The company also burned through $57.62 million in free cash flow, a sharp reversal from a positive figure a year ago. Overall, the combination of missed expectations, weak guidance, and sharply deteriorating profitability led to a negative reaction from investors.
